Application filed March 5, 1909. Serial No. 181,371.

To all whom it may concern:

Be it known that I, HARRY I iioncrr, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in railway-Track Structures, of which the following is a lull, clear, and exact description, such as will en able others skilled in the art to which it appertains to melts and use the same.

This invention relates to railway track structures, and particularly to that type which comprises movable tongue arranged at the intersection of the inside rails of two tracl s and adapted to be moved laterally into alinement with either of said rails so as to form a continuous rail.

My prior patents Nos. 02,451, dated Oc- .ober 27, 1908, and 964,278, dated Novemer 17, 1908, cover railway track structures of the type above rei'erred to, and one object of my present invention is to provide a novel forir oi base plate nd movable tongue for tree: structures of t 118 character.

Another object to provide a railway trac structure of the character described having wheel-operated members i'or correcting inisplacement oi the tongue, which members are so constructed that they will cooperate with perfect or imperfect or double flanged wheels.

Another object is to provide a railway tree: structure of the type above referred to comprising switch-points, means tor causing the tongue to move when the switch-points are shifted, and a wheel-operated member connected to the switch-points in such a manner that said switch-points will be moved into proper position in case the switch point-shifting mechanism has not positioned them properly, and also held locl-zed in this position while a train is passing through the switch.

Other objects and desirable features of my invention will be ereinaiter pointed out.

Figure 1 is a di grammatic view of a railway tracl: structure embodying my present invention; 2 a detail vertical sectional "iew of one of the wheel-operated members and shows perfect wheel traveling on the rail with wh ch said wheel-operated member cooperates, i 3 is a view similar to 2, and shows an iinoeriect or double-flanged wheel traveling on said rail;

is an enlarged top plan view of the movable tongue,

the wheel-operated member for correcting,

misplacement of said tongue, and also the yielding linlvs that form part of the connection between the tongue and the switchpoints; Fig. 5 is a perspective view of the heel end portion of the base plate; Fig. 6 is a per spective view or" the toe end portion of the base plate Fig. 6 a is a side elevational view of same; Fig. 7 is a vertical sectional view taken on approximately the line 77 of Fig. 5; 8 is a vertical sectional view taken on approximately the line 88 of hi 6; Fig. 9 is a vertical sectional view talfen on approximately the line 99 of Fig. 6; Fig. 10 is a perspective view or" the movable tongue in an inverted position; and Figs. 11, 12, 13 and 14 are vertical sectional views tahen on the lines Referring to the drawings which illustrate the preferred form of my invention, 1 designates a movable tongue arranged at the intersection of the inside rails 2 and of a main line and siding, respectively, and 2 and 3 designate switclupomts that cooperate with the outside rails 3 and 3 of the siding and main line, respectively. The switch-points are connected to a head rod or switch-operating bar l that can be actuated manually, or by some suitable mechanical, electrical or pneumatic means, not shown, and the movement of said rod is transmitted to the movable tongue 1 by means of lens rods 5 connected at one end to bell crane levers 6 to which the head rod is fastened, and connected at their opposite ends to hell crank levers 7 which are connected to the opposite side of the toe end of the movable tongue by means of links 8, bell crank levers 9 and short links 10, as shown clearly in lig. 1. l Vhen the head rod t is actuated to shift the switch points the tongue will be moved imultaneously to bring it into alinement with the other track rail with which it cooperates and thus form a continuous rail. Wheel-operated members 12 and 11 are arranged alongside of the rails 2 and 3 adjacent the toe end of the movable tongue, and said wheel-operated members are connected by means of rods 14: to the bell crank lovers 9 so as to correct misplacement of the tongue in case the tongue-actuating means fails to move the tongue into its'proper position. A wheeloperated member 15 is also arranged alongside of the track rail 23 adjacent the switchpoints, and said member is connected by means of a rod 16 to one of the bell crank levers 6 to which the head rod is fastened, so as to correct misplacement of the switchpoints in case the means which shift same to close the siding fails to move the switchpoint 2 tightly against the rail 2 with which it cooperates.

The wheel-operated members 12 and 13 and also the wheel-operated member 15 are carried by pivotally mounted links hereinafter described, and said links are so arranged that the wheel-operated members lie approximately flush with the treads of their cooperating rails when the movable tongue and switch-points are in proper position. Whenever the movable tongue or switch-points are in an improper position said wheel-oper ated members project slightly above the treads of the rails with which they cooperate so that the wheels of an approaching train will depress said members and move them longitudinally so as to complete the movement of the tongue operating means and the switch-point-operating means and thus arrange said tongue and switch-points in proper position before the wheels of a train strike same. F or example, suppose that when the head rod 4 is shifted in the direction indicated by the arrowa in Fig. 1 to close the siding, said head rod fails to move the switch-point 2 tightly against the rail 2 This would cause the wheeloperated member 15 to come to rest'in such a position that it would be engaged and depressed by the Wheels of the next train that approaches the switch, the movement which said member received from the wheels of the train causing the head rod to move far enough in the direction indicated by the arrow in ig. 1 to bring the switch-point 2 into its proper position up against the rail 2 and thus close the siding. If the head rod 4 fails to move the switch-point 3 against the rail 3" when said head rod is shifted in the o posite direction to open the siding the whee -operated member wili come to rest in such a position that it willbe engaged and actuated by the next train that approaches the switch and thus cause the switch-point 3 to move into its correct position. This wheel-operated member 15 also holds the switch-points locked while the train is passing over them, for the head rod and wheel-oper ted member are connected together in such a manner that it will be impossible for the switchpoints to move laterally while the train is passing over the wheel-operated member 15. The connection between the head rod and movable tongue causes said tongue to be shifted simultaneously with the switchpoints, as previously described, but if said connection should break, or if, for any other reason, the tongue should fail to move to its extreme position in alinement with either the rail 2 or 3, the wheel-operated member that cooperates with the track on which the approaching train is traveling, will come to rest in such a position that said ap roaching train will depress it and move it ongitudinally, and thus complete the movement of the tongue or remove it into its proper position before the wheels engage same.

The long rods 5 which form part of the connection between the movable tongue and the switch-point'shifting means, are provided with yielding links A that permit the tongue to move without affecting or chang ing the position of the switch-points, thus enabling a train on the siding to trail through from the heel end of the tongue when said tongue is in alinement with the main line rail, or a train on the main line to trail through from the heel end of the tongue when the tongue is in alinement with the siding rail. The function of these yielding links is the same as that of the yielding links shown and described in my prior patent No. 904,278, ahove referred to, but as the yielding links herein shown are of novel construction, I will specifically describe same. Each of said links comprises a cylinder 17 provided with removable ends or heads 18 and 18 having external screv threads that cooperate with internal screw-threads on the cylinder 17 so as to enable said heads to be removed easily. Each of the rods 5 consists of two sections, the short section 5, which is connected to the bell crank lever 7 passing freely through a tubular-shaped guideway 19 on the head 18 of the cylinder, and the other section of said rod passing freely through a similar guideway 19 on the other head 15 of the cylinder. The section 5 is provided at its inner end with an adjustable stop 20 that limits the outward movement of said section but does not interfere with the inward movement thereof. The long section of the rod that projects through the head 18 in the cylinder is provided with an adjustable stop 21 that cooperates with a spring seat 22 loosely mounted on the rod and bearing against a coiled expansion spring 23 whose opposite end bears against the head 18 of the cylinder, the cylinder being provided at approximately its center with a stationary stop 24 which the spring seat 22 normally engages. The head 18 can be adjusted to vary the tension of the spring 23 and the stops 20 and 21 on the sections of the rod 5 can be adjusted so as to take up any slack in the tongue1noving mechanism.

The base plate B on which the movable tongue 1 is mounted, is provided with a number of bearings 25 on which the tongue slides, and said base plate is provided at its toe end with an integral portion C to which the track rails 2 and 3 are connected, and at its heel end with an integral portion D to which the rails 2 and 3 are connected, said rails forming continuations of the inside rails 2 and 3.

As both of the rail-attaching members C and D are of substantially the same construction I will describe only the mentor D. This member is formed integral with the hase plate and is provided on its sides and top with ribs 26 against which the web-s and under sides of the heads of the rails 2' and 3 bear. The lase plate is also provided with a number of rihs 26 on which the base flanges of said rails bear. Portions of the ase flanges of said rails are cut away so that the remaining portions of said l ase flanges can project into grooves 27 formed in the sides of the member D adjacent the point where it is connected o the hase plate, and said member D is provided at approximately its center with recesses 28 which receive extensions on the base flanges of the rails, as shown in dotted lines in Fig. 7. The object of providing the member D and the base plate with the ribs 26 and 26, respectively, is to provide for variations in the dimensions of the rails and also to enable the rails to be lined up properly. For example, if the rails do not fit snugly against the member D the ribs on said meinher or the ril-s on the h ase plate can he chipped off enough to make the rails fit snugly against the meinher D with their treads in the proper horizontal plane. The recesses 28 in the inemtcr D into which the extensions on the base flanges of the rail project, prevent the rails from creeping longitudinally, and the overhanging portions of said memher D, which are formed by the grooves 27 in the sides of said member, bear upon portions of the lzase flanges of the rails and thus prevent the rails from moving upwardly or vertically relatively to the base plate.

The base plate is provided with a number of integral stops 29, 30 and 31 that project into cooperating pockets 29 30 and 31 on the under side of the tongue 1 so as to limit the lateral movement of said tongue. The stop 31, that is located adjacent the toe end of the tongue, and also the intermediate stop 30, are provided with laterally projecting portions that cooperate with inwardly projecting flanges 32 on the side walls of the pockets into which said stops project so as to overcome any tendency of the tongue move upwardly from the base plate. As shown in Figs. 8 and 12 the bearings 25 on the base plate that are located adjacent said stationary stops, do not extend clear up to same but terminate a short distance from the sides of said stop so as to form grooves 33. The lower edges of the inwardly projecting flanges 32 in the pockets of the tongue are also cut away at 34, as shown in Figs. 12 and 14 so that when the tongue is in either of its extreme positions against the stationary stops there will be a slight clearance between the base of each of said stops and the portion of the tongue with which it cooperates, thereby providing for inequalities in the tongue and base plate and also eliminating the possibility of dirt becoming clogged between the stops and tongue and thus preventing the tongue from moving into its extreme positron.

The rail-attaching member C at the toe end of the base platis provided with laterally projecting lugs 28 that in notches in the base flanges of the rails, as shown in Figs. 6 and 9, so as to prevent longitudinal creepage of said rails. The base plate is also provided on its under side with depending lugs an, as shown in .c'igs. 6 and 9, that reinforce and strengthen that portion of the base plate which is located underneath the meeting ends of the track rails 2 and 3 and the movable tonguc. These lugs 3% also perform another function; namely, they prevent a track tie from being placed directly under the toe of the tongue and the terminals of the rails 2 and 3, as l have found in practice that better results are obtained when the track ties are located a short distance from the meeting ends of the tongue and rails, as shown in 6*. it is also preferable to arrange the track ties in this manner so that a space or channel will be provided for the links 8 and also to enable the pins which connect the bell crank levers 9 to the operating mechanism, to be inserted upwardly from the underside of the base plate, as hereinafter described. The tongue is provided at its inner end with an integral. pivot in 35 that projects into a socket 36 formed in the railattaching member D, and the heads of the rails 2 and 3 are so formed that they project over the upper end of said pivot pin and thus prevent the heel end of the tongue from rising upwardly. The tongue herein shown is practically hollow and is provided with a number of cross webs 37 that strengthen same and also form the end walls of the pocl 1- ets into which the stationary stops on the base plate project.

The short linlts 10, which connect the toe end of the tongue to the bell cranl: levers 9, are fastened to laterally projecting lugs 38 on the tongue, and the top faces of said lugs are inclined downwardly toward the base plate so that a wheel that has become derailed or slipped from the tongue onto the base plate, can ride up over one of said lugs onto the track rail with which the tongue alines, there being suliicient metal in these lugs to prevent the Wheel from shearing them off as said wheel rides up over the lug. The short rods 14 that connect the wheel-operated members 12 and 13 to the bell crank levers 9, are camber-ed slightly so that they can bow outwardly or bend outwardy slightly in case the tongue reaches its extreme limit of movement before the wheel-operated member has been fully depressed. In other words, these rods are so formed that if they are subjected to abnormal strains they will bend. outwardly intermediate their ends and thus prevent breakage of any of the members which they actuate. I prefer to provide each of the rods 14 with an upwardly projecting guiding lug 40 that bears against the wheel-operated member with which said rod cooperates, and thus tends to force said member inwardly toward the track rail alongside of which it is arranged. The opposite ends of the wheel operated members are prevented from moving outwardly away from the track rails by means of guides 41 that are connected to the track ties. To overcome the possibility of a bolt, nut or other rigid object being wedged underneath the base flange of either of the rails 2 and 3 or between the base flanges of the rails and the bell crank levers 9, I have provided the toe end of the base plate with upwardly projecting flanges 42 that extend parallel to the rail-attaching member C, as shown in Figs. 6 and 9, the upper edges of these flanges 42 terminating above the ribs on the base plate on which the stationary track rails rest. The outer side face of each of these flanges 42 is curved at 43, as shown clearly in Fig. 9, so that any object or substance that lies in the path of movement of the bell crank levers 9 will be forced upwardly on said curved faces 43 onto the upper sides of the base flanges of the rails instead of becoming wedged between said base flangesand the base plate or between said base flanges and the levers 9. The corners of the bearing 25 on the base plate on which the toe end of the tongue rests, are also cut away at 44, as shown in Fig. 6, so as to provide a clearance for any object that gets in the path of movement of the bell cranks 9. These-bell cranks 9 are pivotally connected to brackets 45 on the base plate, and said base plate is provided with a number of holes 46 located in such a position that the pins which connect said bell cranks to their cooperating links can be arranged in position easily, said pins being inserted from the underneath side of the base plate into the openings provided for them in the bell cranks and their cooperating links. The wheel-operated members 12, 13 and 15 are so formed that they will cooperate with a perfect wheel and also with an imerfect or double-flanged wheel. It is well- :nown that the tread surface of the car wheel becomes concaved or double-flanged after it has been in use for a short while on account of the wearing away of the tread of the wheel and the lateral movement of the wheel relatively to the rail which. has a smaller tread than the wheel, and I have therefore provided the tread surface of each of said wheeloperated members with a portion that is adapted to be engaged by the tread. of a perfect Wheel and a portion that is adapted to be engaged by the tread of an imperfect saasee or double-flanged wheel. As all of the wheel-operated members are of substantially the same construction I will only describe the member 12. Said member is carried by a plurality of pivotally mounted links 47 that are carried by brackets 48 connected to the rail 2, as shown in Fig. 2, the tread surface of said wheel-operated member consisting of a portion 49 that is adapted to be engaged by the tread of a perfect wheel, as shown in Fig. 2, and also a portion 50 that conforms to the outside flange or outer eoncaved portion of an imperfect wheel and is adapted to be engaged thereby, as shown in Fig. 3. By forming the wheeloperated member in this manner I can make it heavy enough to withstand the strains and shocks to which it is subjected, and also insure that it will be operated by either a perfect wheel or an imperfect wheel. I prefer to bevel the end portions of the tread surface of the wheel-operated member at 51, as shown in Fig. 4, so as to gradually guide an imperfect wheel onto the portion 50 of the tread surface of said member that conforms to the outer flange of an imperfect wheel. site sides of the tread surface of the tongue at 52, as shown in Fig. 4, so that if said tongue is not in exact alinement with either of the rails 2 or 3 the approaching wheel will strike the beveled portion of the tongue and shift it laterally into exact alinement with the rail.

1 have herein used the term inside rails merely for the purpose of designating the ract rai s wii 1 wiici ne m v u t l 1 ti 1 l t o able tong e cooperates and I do not wish it to be understood that my invention is limited to the type of track structure herein shown for this same idea could be embodied in a crossing.
